Final answer:
A urethral stricture is the narrowing of the urethra, which can be caused by various conditions, including tumors and prostate gland enlargement, and may lead to symptoms like reduced urine flow and pain during urination.
Step-by-step explanation:
The term for a narrowing of the urethra is known as a urethral stricture. This condition can occur due to various reasons, such as urethral tumors, urinary bladder tumors, enlargement of the prostate gland, or from a previous injury or infection. The symptoms of a urethral stricture may include a decreased urine flow, pain during urination, and potential urinary tract infections (UTIs). It is crucial to diagnose and treat urethral strictures as they can lead to complications, including bladder and kidney damage.
The urethra's function is to transport urine from the bladder to the external environment. A urethral stricture interferes with this function, leading to a range of urinary symptoms. Treatment for a urethral stricture may involve procedures to stretch or surgically open the narrowed area or the insertion of a urinary catheter to bypass the obstruction.
